Title: Manufacture of high tension and high toughness wire rod having superior delayed fracture resistance
Inventor: KATO TAKEHIKO
IPC: C22C38/58
Filed: 1986-05-13
Abstract: PURPOSE:To remarkably improve the delayed fracture resistance by forming a decarburized layer in the surface part of a high Si steel and hardening the steel. CONSTITUTION:The composition of a steel is composed of, by weight, 0.05-0.3% C, 1-3% Si, 0.5-2.5% Mn, one or more among, <=0.2% Nb, <=0.2% Ti, <=0.2% V, <=2% Cr, <=0.5% Cu and <=2% Ni and the balance Fe with inevitable impurities. When the steel is soaked before hot rolling, it is soaked in the austenite range after slow heating from the Ac1 point to the Ac3 point at 5-20 deg.C/min heating rate. Hot rolling is finished in the austenite range and water hardening is carried out to obtain a steel wire rod having a decarburized layer in the surface part and a martensite or martensite + ferrite structure as the internal structure, e.g., a steel wire or bar.

Inventor: KAWABATA YOSHIO
IPC: F16B37/04
Filed: 1989-04-27
Abstract: PURPOSE:To eliminate local deformation and strain on a metal plate by forming a cylindrical projection on the seat surface side of a nut main body, forming a divergent inclined surface on the internal circumference of its opening end, and forming a ring groove on the external circumference of the cylindrical projection. CONSTITUTION:A clinch nut 1 is so constructed that a cylindrical projection 5 is provided on the seat surface 4 side of a nut main body 2 concentrically with a screw hole 3 and projectedly from the seat surface 4. The internal circumference of the cylindrical projection 5 is larger in diameter than the major diameter of the screw hole 3, and a divergent inclined surface 6 is formed on the internal circumference of its opening end 5a. Also, a divergent ring groove 7 recessed from the seat surface 4 is formed on the external circumference of the cylindrical projection 5. When the cylindrical projection 5 of the nut main body is crimped, any deformation and strain will not be produced locally on a metal plate 11. Thus, the nut 1 can be fixed stably and securely on the metal plate 11.

Abstract: PURPOSE:To stop continuous run for a long time and to save energy, by compulsively turning off an auxiliary relay within a prescribed time after the operation regardless of the temperature state, in a temperature regulator for an air conditioner and the like. CONSTITUTION:When the relation of input voltages of a comparator 3 is - input > + input, the output voltage of the comparator 3 is zero and when - input < + input, the output voltage is determined with resistors 4, 5 and 6. When the output of the comparator 3 becomes 0 volt, a count circuit 18 starts counting. If the temperature of a thermister 1 changes before the lapse of setting time T and the relation of - input < + input is obtained, a relay 12 is turned off with a NOR circut 17. Unless - input < + input is obtained even with the elapsed set time T, a transistor 14 is turned off with an output pulse signal of the circuit 18, the - input voltage is made to 0, and the relation is compulsively changed into - input < + input. Thus, the relay 12 is turned off, the set voltage of the input is changed and the continuous running time is suppressed to a maximum T.

Abstract: PURPOSE:To permit to form a heat exchanging body having various sizes, shapes and performances by a method wherein the plate type body, made of ceramics, and the heat exchanging element, consisting of a tube, are connected to the through-hole of a frame body through an elastic body of rubber. CONSTITUTION:In the heat exchanging element 11, a plurality of tubes 21, made of ceramics, is penetrated through the plate-like body or a fin 31, made of ceramics, and both of them are fixed mutually by each other. According to this method, heat conductivity is large and high fin efficiency is obtained while the dew-point corrosion by sulfuric acid may be avoided. The frame body 41 is bored with the through-holes 45 at the same position as the tube 21 and a gap between the frame body 41 and the outer diameter of the end 22 of tube is fitted with the elastic body 51 of rubber. Further, the tube end 22 of a different heat exchanging element 11 is fitted into the elastic body 51 and, thus, a plurality of heat exchanging elements 11 are connected with each other. Accordingly, the outflow leakage of fluid may be prevented and shock vibration may be absorbed. On the other hand, thermal deformation may be absorbed even when a multitude of elements 11 is connected and the assembling work may be facilitated.

Title: Speed controller for dc motor
Inventor: OOTA MITSUHARU
IPC: H02P7/288
Filed: 1982-06-24
Abstract: PURPOSE:To smoothly control the speed of a DC motor by dividing a reference voltage via resistors. CONSTITUTION:A reference voltage Vref of a reference voltage power source 12 is divided by resistors 16, 17, and the dividing point is connected to a comparator 13. The comparator 13 compares the counterelectromotive force Ea of a DC motor 1 with the reference voltage, and controls the base currents of a transistors 9-11 which form a current mirror in response to the differential voltage of both. Since the transistors 9-11 are not saturated in this manner at the control maximum torque time, the speed control of the DC motor can be smoothly performed, and can be controlled to low rotating speed.

Filed: 1982-06-28
Abstract: PURPOSE:To ensure the demodulation of information, by adding plural differential signals having a prescribed relation with a transmission data to the same PN code, and modulating carriers different in frequency individually with added plural signals, and transmitting the result. CONSTITUTION:An information signal (transmission data) S(t) and plural differential signals u(t), u(t-T) having a prescribed relation with the transmission data S(t) at the transmission side are added to the same PN code and carriers f1-f3 having different frequency individually are modulated with the added plural signals and the result of synthesis is transmitted from an antenna 34. A receiver separates a receiving signal received at an antenna 41 into the SS modulating wave having the center frequencies of f1-f3 and the PN code component is erased by applying the signal to balancing modulators 45-47 for inversely spread. In demodulating the output of the modulators 45-47 at two- phase demodulators 48-50, the output is converted into the original signal S(t), allowing to reproduce the transmission data.

Concretely, the reaction is carried out at <=10 deg.C until the conversion of the raw material reaches at least 30mol%, and is completed at >=60 deg.C. Especially, the reaction temperature is maintained at <=10 deg.C until the conversion reaches at least 30mol% and at <=30 deg.C until it reaches at least 60%, and the final reaction temperature is selected to >=60 deg.C. USE:Liquid for the various tests of electronic parts, refrigerant and insulator for high-potential electric parts, etc.

Title: Manufacture of semiconductor device
Inventor: IIDA TAKASHI
IPC: H01L21/82
Filed: 1990-04-25
Abstract: PURPOSE:To simply correspond with logic change and ensure short TAT by preparing a pattern for logic correction in a channel part. CONSTITUTION:When an I/O cell group 20 and a standard cell group 11-1N of a semiconductor substrate 10 are laid out, a pattern 30 capable of constituting transistors only by wiring is also laid out. When a diffusion process, an insulating layer forming process, a wiring process, etc., are executed, the processes before the wiring process are executed for the pattern 30 together with the I/O cell and the standard cell. The later wiring processes, however, are not executed for the pattern 30 but executed only for the I/O cell and the standard cell. When imperfect logic design and the like are found and logic change becomes necessary, gates for the logic change are formed by using the pattern 30 and built in the standard cell. Thereby the time necessary for correction, and masks and semiconductor devices to be scrapped can be remarkably reduced, and TAT is also improved.
